They had a whole lot of different down jackets when I went into TJ Max today, but the $50 "Big Chill Tech" "Packables" looked like a steal. There's no fill weight listed on the tags, but the women's XL I got weighs 8.5 oz when in the stuff sack it came with. If I had to guess I'd say 650-700 fill based on the feel of it compared to other jackets I've tried on. It has a full front zip and the TJ Max near me had it in solid black and grey with pink trim.

Also check out the athletics section for women's running clothes (<$10 for synthetic shirts) and the men's socks for Icebreaker wool hiking socks.
